This is an HTML+RDFa representation of metadata describing this Web-addressable resource.
Why Is This Important?
The property (attributes and values pairs) links on this page unveil a different kind of link, one which enables the following on HTTP networks such as the Web:
Unambiguous identity for entities (aka. strong identifiers)
Implicit binding of an entity and its metadata via strong identifiers
Multiple metadata representations that enable a variety of presentations
High precision Search and Find queries that simply use the metadata documents (by referencing entity URIs) as the query's Data Source Name
How Do I Discover Alternative Metadata Representations?
This document exposes metadata in the following formats: (X)HTML+RDFa, Turtle, N3, RDF/JSON, or RDF/XML. In the most basic form, you can simply view the (X)HTML source markup of this page, and go directly to the <head/> section which contains a <link/> tag with relationship and type properties for each format.
In addition, you can also explicitly request a desired metadata representation for a given resource via HTTP GET requests that use the entity's strong identifier as the call target.
How Can I Expose My Web Resources In This Manner?
Simply include the following in the <head/> section of your (static or dynamically generated) (X)HTML page:
<link rel="alternate" title="My Data in RDF Linked Data form"
type="application/rdf+xml"
href="http://linkeddata.uriburner.com/about/id/<this-page-URL>/>"
How Is This Related To The Linked Data Meme?
As stated above, the links in this page expose strong identifiers for its primary topic, secondary topics, attributes, and some values. These links, via implicit association, act as conduits to their metadata-bearing documents, in a variety formats.
NVIDIA JetPack 4 reached its end-of-life (EOL) in November 2024, marking the end of security updates for this widely deployed stack. JetPack 4 has driven innovation in countless devices powered by NVIDIA Jetson, serving as the foundation of edge AI production deployments across multiple sectors.
But now, the absence of security maintenance creates risk for businesses with deployed JetPack 4-based deployments. Devices running unmaintained software can quickly become vulnerable to known exploits. This blog will walk through your options for maintaining security with Ubuntu Pro, and outline the path toward modernizing your stack with the certified NVIDIA Jetson Orin series.
What does JetPack 4âs EOL mean for you?
As of November 2024, JetPack 4 is no longer maintained by NVIDIA. This means the end of security updates, bug fixes, and support for all JetPack 4.x versions and corresponding Jetson Linux releases.Â
This marks an important shift. JetPack 4 users are now fully responsible for maintaining the security of their own deployments or upgrading to newer JetPack versions. Without vendor-backed updates, maintaining system integrity becomes increasingly difficult, especially for production fleets.
For organizations who wants to continue using JetPack 4 for deployment, this raises two pressing questions:
Whatâs the best migration path to a supported, future-proof platform?
How do you keep existing devices secure in the short term?Â
Long term solution: Ubuntu certified with +10 LTSÂ
Your best long-term path is migration. The Jetson Orin series is the future of AI at the edge â and now comes with official Ubuntu certification.
Canonical and NVIDIA have collaborated to deliver out-of-the-box support for NVIDIA Jetson Orin platforms. Whether youâre using Jetson Orin Nano, Jetson Orin NX, or Jetson AGX Orin, certified Ubuntu brings:
Unparalleled performance: Harness the full potential of the NVIDIA Jetson platformâs AI capabilities with optimized Ubuntu images.
Enterprise-ready security: Benefit from Ubuntuâs robust security features and long-term support.
Seamless development to deployment: Experience a unified environment from cloud to edge, streamlining the AI development process.
Reliable stability on certified hardware: Canonicalâs QA team performs an extensive set of over 500 OS compatibility-focused hardware tests to ensure that every aspect of the system is checked and verified for the best Ubuntu experience.
With Ubuntu on Jetson Orin, developers gain a consistent and modern Linux experience â the same tools used in cloud and desktop environments are now available on the edge. This continuity simplifies development, accelerates time to market, and maximises device lifespan.
Immediate migration to Jetson Orin may not be feasible for every team. Legacy deployments, supply constraints, or integration timelines can slow things down. Â
JetPack 4 is built upon Ubuntu 18.04 LTS. This Ubuntu userspace includes more than 23,000 packages â such as Python, OpenSSL, systemd, and bash â that are integral to the systemâs functionality and your developed application.â The standard support window for these packages ended in 2023, so they are no longer receiving security maintenance.Â
Canonicalâs Ubuntu Pro offers Expanded Security Maintenance (ESM) for Ubuntu LTS releases, ensuring continued security updates beyond the standard support window. For JetPack 4 users, enabling Ubuntu Pro gives access to updates from the ESM PPA until 2028, so that packages from the Ubuntu userspace remain secure.Â
These updates provide critical security patches for the Ubuntu 18.04 LTS userspace only. The JetPack 4 kernel (based on the Linux kernel 4.9) remains outside of the scope of the service â so migration should still be the long term goal â but ESM can help you maintain operational security and system stability while you transition to newer platforms.
Ubuntu Pro also includes popular applications such as the Robot Operating System (ROS), where Canonical provides services such as ROS ESM for the upcoming EOL of ROS 1 Noetic.
| Remember to always test your updates before deploying them to end devices.Â
Small number of devices: purchase ESM through the Ubuntu Pro store
For a few devices, purchasing ESM directly through the Ubuntu Pro Store is straightforward. Simply go to the Ubuntu Pro Store and complete your purchase.Â
Larger fleets: purchase ESM through Canonicalâs Ubuntu Pro for Devices
Ubuntu Pro for Devices grants you access to the Ubuntu Pro subscription (and so to ESM), applying a beneficial discount-based model depending on your compute module.
Security updates during ESM are accessed via a dedicated repository. This requires a subscription token, which you can get through your Ubuntu Pro account after subscribing.
To enable ESM, you just need to follow the following instructions in your welcome email:Â
Install the Ubuntu Pro client
Attach your token to your JetPack4 machine
Activate ESMÂ
Run apt upgrade will now allow you to install available updates
With JetPack4 EOL, businesses must proactively manage their devices. Working on an unsupported release introduces security risks no organization can afford. Although migrating to a newer Ubuntu Certified Jetson Orin remains our primary recommendation, we acknowledge the challenges involved. When migration isnât immediately feasible, activating ESM provides some security maintenance.
